### 3. SD Card Check&#x20;

c) The installation package name does not contain suffixes like (1).\

\
d) After downloading the package, safely eject the SD card from your computer.

### 4. Adapter Check：

a) The SD card is inserted into the adapter before plugging in the original power cable.

b) The adapter is connected to a power socket, NOT a computer USB port.

c) The indicator light is blue after plugging the original power cable into the adapter.<br>

### 5. If the power was disconnected or the adapter was disconnected from the Titan during the file copying process:

a) Repeat the upgrade attempt on the Titan Series.&#x20;

b) If the upgrade fails but the device shows the latest version, increase the last digit of the installation package file name by 1 (4.9.0.zip 4.9.1.zip).\
